1、Designation: C 615 03Standard Specification forGranite Dimension Stone1This standard is issued under the fixed designation C 615; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses in

2、dicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope1.1 This specification covers the material characteristics,physical requirements,

3、 and sampling appropriate to the selec-tion of granite for general building and structural purposes.1.2 Granite dimension stone shall include stone that issawed, cut, split, or otherwise finished or shaped, and shallspecifically exclude molded, cast, or otherwise artificiallyaggregated units compose

Classification4.1 Granite dimension stone under this specification shall begranite used for:4.1.1 Exterior and interior cladding of buildings and struc-tures;4.1.2 Curbstone, paving, and landscape features;4.1.3 Structural components having es

7、tablished dimensions;4.1.4 Grade separations and retaining walls; and4.1.5 Monuments.5. Physical Properties5.1 Granite supplied under this specification shall conformto the physical requirements prescribed in Table 1. See 5.1.2for possible variations from this table.5.1.1 The minimum compressive str

8、ength, flexural strength,and modulus of rupture shall be based upon the minimumaverage strength of specimens tested in four conditions: wet ordry and parallel or perpendicular to rift.5.1.2 The physical properties given in Table 1 representproperties of granite that have a history of successful use

9、forgeneral building and structural purposes. Granite with strengthor abrasion resistance less than the minimum values prescribedin Table 1 may be used provided that competent engineeringauthority has evaluated relevant characteristics of the granite.This evaluation shall consider both structural eff

10、ects andmaterial characteristics such as durability, permanent volumechange, modulus of elasticity. thermal expansion, and the like.5.2 Granite shall be sound, durable, and free of spalls,cracks, open seams, pits, or other defects that are likely toimpair its structural integrity in its intended use

11、.5.3 Granite shall be free of minerals that may cause objec-tionable staining under normal environments of use.5.4 The desired color and texture, with their permissiblenatural variations in material characteristics for all material tobe produced for the project, shall be established by controlsample

22、 of the No. 60 Alundum abrasive, Norton, has indicated that the formula for Norton treatment 138S has beeen changed. The new abrasive is currently moreaggressive, resulting in lower abrasive hardness values (Ha) than when the standard was initially established. As such, care should be taken when int

23、erpreting Havaluesfrom tests using the new abrasive, particulary with regard to current ASTM stone standard specification requirements for abrasion resistance, which were developed whenthe original abrasive was still in use. Committee C-18 is actively studying alternatives to address this issue.CAbrasion Resistance Test Method C 1353 will eventually replace Test Method C 241 and it is not necessary to perform both tests. Availability of the proper equipmentand materials by the testing laboratory may determine which test is performed.C615032
